Plus one on the dont get a set unless the set has exactly what you want. Most dont, so youre better off selecting alacarte and starting with a good 8 or 10 chefs knife, a paring or petty, and a decent 10 serrated bread knife.
The KO chefs knife has a handle and bolster specifically designed for a pinch grip, for user with a certain hand size and a blade with a substantial belly curve. Some will swear by it, while others (like myself) will swear at it. I found it uncomfortable and my wife found it impossible to hold within moments of trying it. I believe a handle that enforces the use of a pinch grip (only), and a blade with that much curvature is unnecessary and very limited. Any chef knife (including the other shuns) with normal handle and a blade with less (or a lot less) curvature will be more versatile.
